Abstract

PURPOSE: To transfer asynchronous data by one control line, by transmitting data to a data line through the discrimination of the state of a strobe line at the transmission side and transmitting a pulse to the strobe line at each data transmission.
CONSTITUTION: When a selection line 18 between a controller 11 and a terminal 12 is at a low level, a signal on a data line 13 represents an address, the signal in the data line 13 is automatically fetched into an address detector 21, and when it is detected as a self-address, the data on the data line 13 is fetched. The device 11 discriminates the state of a strobe ST line 19 through an inverter 23 and the ST line 19 is made to a low level when the line is in a data transmitting state and set to a high level in a vacant state. The device 11 transmits a pulse to the ST line 19 via an inverter 24 every time data is given to the data line 13. When a device 12 receives a pulse of the ST line 19 by a detector 21 detecting an address, the ST line 19 is kept to the low level of transmitting state via an FF25 and an inverter 27 and the transmitted data is fetched into a processor 22.
